I know this general topic has been brought up here before, but I hope you will indulge me on this particular wrinkle:

I have read the 1st and 3rd editions of Security Analysis. I am pretty sure I do not want to read the 5th or the 2nd editions (although someone could argue me into reading them, with enough effort). However, I am unsure about whether or not I should read the 4th edition. Does anyone who has read the 3rd edition have an opinion on this?

As you know, it is a pretty major undertaking to read any of the editions, and there are many other interesting things on my reading list. However, I don't want to miss a "don't miss" opportunity either.--Rockythecat
